Yes, we are about to release the Power System Manager (PSM). It has a higher voltage range than the Multi Battery Manager, switching capability and low voltage protection. Each battery requires a Power System Manager and you can parallel as many batteries as you like.
Basically, the power source with the highest voltage will be used until all power sources are balanced where they are drawn on equally.
You can also combine the PSM with an external power source to create a hybrid power system where the external power is used most of the time, while the battery cuts in during heavy current draw.
